Having captured the Joker, offed Two-Face, faked his own death, and passed the crimefighting torch to a new generation, Bruce Wayne is a man with a lot of time on his hands. So what better way to enjoy retirement race this street-legal Tumbler across the US in the annual Gumball 3000 rally?

Designed by Team Galag and built by Parker Brothers Concepts, this replica of the famous film vehicle is fit for the 3000 mile cross-country supercar trek. It's packing a 450-bhp, 6.2L V8 with a triple-digit top speed under the hood.

“The main reason behind doing the Tumbler was that we wanted to bring back a little originality and fun to the Gumball 3000, something it was always known for," Team Galag wrote on their website. "We wanted to capture the spirit of movies and cartoons such as Cannonball and Wacky Races, while keeping with the cool and rock and roll image of the rally.”

Though at 2.5 tons and wider than a Hummer H2, the team will need Bruce Wayne's checkbook to get that beast across the finish line. [Motor Ward via Jalopnik - Images: Team Galag]
